Silent Knight SK-PHOTO-R-W Photoelectric Smoke Sensor

Silent Knight SK-PHOTO-R-W Photoelectric Smoke SensorModel SK PHOTO R W is a plug in type smoke sensor that combines a photoelectronic sensing chamber with addressable analog communications. When used in duct applications with a DNR(W), testing can be done remotely using approved System Sensor test accessories, eliminating the need for a test coil. The sensors transmit an analog representation of smoke density over a communication line to a control panel. Rotary dial switches are provided for setting

By delivering consistent samples from across the duct’s full width

Three programmable Form C relays (factory programmed for alarm

ANSI/UL 1971 and/or ANSI/UL 1638 listed for use with fire protective systems and are warranted for three years from date of purchase

the KS-PS differentiates particles that are not representative of actual smoke
